HAIR-DRYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 778,888, dated January 3, 1905.

Application filed July 29, 1904. Serial No. 218,748.

To all who/n it natty concern.-

Be it known that we, OTTO PETER, manufacturer, residing at 5 Stubenstrasse, and HER- BERT voN KEMPsKI RACOSZYN, civil engineer, residing at 27 Grossestrasse, Osnabriick, in the Kingdom of Prussia, German Empire, both subjects of the German Emperor, have invented certain new and useful Improvements in Hair-Drying Apparatus, of which the following is a specification.

The hair-driers now used by hair-dressers and others for drying damp hair are mostly so constructed that the air heated by gas, spirit, or otherwise is conveyed to the hair by means of fans or ventilators, and the very hot air rapidly produces a dry and undulated hair. Those heating devices have besides others the drawback that the'gas and spirit cause an unpleasant smell and make the air too dry, and, further, that the heating cannot be sufliciently regulated. Moreover, gas cannot be used in places where there are no gasworks, but, as is frequently the case nowadays, electric-light plants. The said drawbacks we have removed in an air-warmer on a hair-drier which by means of electric light heats the air so rapidly and strongly that the hair-drier is at once ready for use. This new air-warmer is, moreover, easy to handle, causes no unpleasant smell, produces a pleasant, warm, and dry hair, and maybe used with absolute safety, as it can cause no fire.

On the accompanying drawings, inwhich similar figures refer to similar parts throughout the several views, Figure 1 shows ahairdrier according to the present invention in a perspective view. Fig. 2 is a vertical section through the air-heater itself. Fig. 3 is a horizontal section through the latter, thereby showing the driVing-motor, together with the regulator of same, in side view. Fig. 1 is a front view of said regulater or distributer, partly in section. Fig. 5 is atop view of the latter when removed from the motor, and Fig. 6 illustrates schematically the arrangement of the conduits for the motor as well as for the air-heating lamps.

According to the embodiment of the invention represented as an example in the drawings, the object of the invention consists of the standard 1, which is adjustable in height, and of the heating device 2, carried by said standard, and also of the electric motor 3, driving the ventilator, and of the scoop A, on which the hair is placed, as well as the flexible hot-air tubing 5.

The standard 1, the electric motor 8, the scoop 1, and the tubing 5 can of course be of any suitable construction, the essence of the invention consisting in the construction and arrangement of the part 2. Said part 2 consists, according to the constructional example represented in the drawings, of two cylinders 7 8, arranged concentrically to one another, which are completely closed on the one hand by the cover 9 and on the other hand are partially closed by the rings 10, which leaves the inner cylinder 8 open. In the ring-shaped space 11 thus formed the electric glow-lamps 12 are mounted on the ring-shaped cover 10 in a suitable manner and in a suflicient number; Close to the open end of the inner cylinder 8 the ventilator 14: is driven in an apartment 13 of suflicient size by means of the electric motor 3. The outer cylinder 7 isadvantageously formed with a double wall, the

space between its two walls being filled with a substance conducting heat as badly as possible. An auxiliary cylinder 15 is advantageously provided between the glow-lamps 12 and the outer cylinder 7 said auxiliary cylinder 15 leading the dry air entering through the inlet-orifice 16 of the outer cylinder 7 once round the whole heating device before said air passes through the orifice 17 into the auxiliary cylinder 15 and comes actually into contact with the glow-lamps 12. Thereby, togetherwith the help of the partition-wall 18, the heated air is drawn in by the ventilator 14 in such a Way that all the glow-lamps 12 must first be passed over by this air beforethe same can fiow, by means of the said Ventilator, into the scoop 4 or the pipe 5. In order that the heating of the air may be still more intense, hollow rods 19, filled with sand, if desired, are provided in the interior of the cylinder 8, said rods being advantageously fixed crosswise with regard to one another.

The regulation of the heating of the dry air as well as the actuation of the whole apparatus can be effected by the switch or regulating device arranged on the base of the electric motor 3, as shown in Figs. 4 and 5. This consists of a rotary contact 20, which is fitted with a fork-shaped contact-lever 21, so that the motor 3 can be switched in alone, but not the group of glow-lamps 12. The arrangement of the fork-contact 21 is such that on closing the circuit of the group of glow-lamps by the one prong of the fork the end of the second prong comes exactly on the contact for the motor 3 and the latter is set in rotation, under all circumstances, before the switching in of the group of glow-lamps. A dial 22 on the switchregulator 6 allows, moreover, the position of the contact 20 to be ascertained at any time without trouble. Moreover, several resistances 23 are provided in the switch-regulator 6, which are under the influence of a special lever 24, so that according to the setting of the same by hand the motor 3 can be set running more or less quickly.

What we claim is 1. In an apparatus for drying hair, the combination of two concentric cylinders each provided with an orifice, a cover closing both of said cylinders at one end, a ring-shaped cover closing the space between the two cylinders at the other end, a plurality of glow-lamps arranged in the ring-shaped space between said cylinders, a ventilator at the open end of the inner cylinder, means for driving said ventilator whereby cold air is drawn into the outer cylinder, is heated by said lamps and drawn through the inner cylinder and means for applying said air to the hair, substantially as described.

2. In an apparatus for drying hair, the combination of two concentric cylinders each provided with an orifice, a cover closing both of said cylinders at one end, a ring-shaped cover closing, the space between the two cylinders at the other end, a plurality ofglow-lamps arranged in the ring-shaped space between said cylinders, an auxiliary cylinder provided with an orifice and arranged between the glowlamps and the outer cylinder so forming a passage between itself and the outer cylinder running once round the latter, a partition-wall between the auxiliary cylinder and theinner cylinder, a ventilator at the open end of the inner cylinder, means for driving said ventilator whereby air is drawn into the outer cylinder through the orifice in the same, along the above-mentioned passage, through the orifice in the auxiliary cylinder, over the surface of the lamps, through the orifice in theinner cylinder into the latter and through the open end of the same, and means for leading said air to thehair to be dried, substantially as described.

In witness whereof we have hereunto signed our names, this 5th day of July, 190 in the presence of two subscribing witnesses.
